I want to sell my breastmilk-

T. F. • For I know the plans I have you, declares the lord, plans to prosper you, not harm you, plans to give you hope &a future

I have over 300 ounces of healthy frozen breastmilk. I am a healthy, active mom. I over produce for my 6 month old daughter. I was going to throw all of this milk out because my husband stopped me and asked if I had considered selling it? I have donated before but never thought about making money off it. Any recommendations or past experiences? Any advice on how to go about this?
